Safina is a blockchain-based solution that includes:
Black Box - a management server with cryptographic signatures for interacting with the blockchain.
Multi-signature hot wallet in Safina - similar to a blockchain wallet, but users do not need to interact with the blockchain directly. It can be considered as an online payment system, as Safina server is responsible for managing the wallet's private key and sending transactions.
API - for connecting businesses to Safina's multi-signature wallet. Using the API, companies can submit requests for creating Safina multi-signature wallets and conducting transactions with them.
